Herschell Red Rubber Grease is a specialized, non-mineral oil-based lubricant specifically engineered for the assembly and protection of rubber components. Unlike standard petroleum greases—which cause natural and synthetic rubbers to swell, soften, or crack—this vegetable-oil-based formula is completely "rubber-safe."
Technical Specifications
- Base: Vegetable oil with an inorganic thickener (typically Castor-bentone).
- Color: Distinctive Red (for easy identification and to prevent cross-contamination).
- NLGI Grade: 2 to 2.5 (Medium consistency).
- Drop Point: 160°C
- Temperature Range: Effective from -20°C up to +150°C
- Volume: 500g Tub (Product Code: HERS0090).
Key Features
- Material Compatibility: Specifically designed to be compatible with Natural Rubber and SBR (Styrene-Butadiene Rubber) seals.
- Prevents Deterioration: Stops rubber components from "perishing," hardening, or swelling when exposed to hydraulic fluids or environmental stressors.
- Water Repellent: Provides excellent resistance to water washout, protecting metal-to-rubber interfaces from corrosion in damp or humid conditions.
- Non-Toxic: Formulated to be safe for the user and the environment (fully biodegradable).
- Superior Adhesion: Clings well to various surfaces, producing a long-lasting protective film that facilitates "fuss-free" assembly.
Common Applications
- Automotive Braking Systems: The primary choice for lubricating rubber cup seals, O-rings, and boots in brake master cylinders, slave cylinders, and caliper rebuilds.
- Clutch Hydraulics: Used in the assembly of clutch master and slave cylinders to ensure smooth piston movement.
- Suspension & Chassis: Lubricating rubber bushes and gaiters to prevent squeaking and premature cracking.
- Plumbing & Irrigation: Ideal for lubricating O-rings in taps, valves, and pipe connectors (safe for potable water systems).
- Industrial: Assembling various synthetic rubber seals and gaskets in hydraulic machinery.
Usage Tips
- Cleanliness First: Ensure all parts are thoroughly cleaned of old mineral-based grease or grit before applying Red Rubber Grease.
- Apply Sparingly: For O-rings and cup seals, a thin, even film is usually sufficient to ensure a leak-proof and friction-free assembly.
- Strictly for Rubber: While it is a great lubricant for rubber, it is not a substitute for high-load metal-to-metal greases (like wheel bearing grease). Use it only where rubber compatibility is required.
- Storage: Keep the tub tightly sealed and store in a cool, dry place away from direct sunlight to maintain the stability of the vegetable-oil base.
